Specication of Letters Patent.

Patented May 20, 1919.

To all 'whom t may concern:

Be it known that I, JEssE L. FUsNER, a citizen of the `United States, residing at -Wellsburg, in the. county of Brooke and State of West Virginia, have invented certain new and useful Improvements in Oilers, of which the following is a speciiication.

The present invention relates to oilers, and particularly hand Oilers of the type in which the discharge of lubricant can be controlled. f

' One o f the primaryobjects is to provide a practical structure of this character, which islat the same time simple in its make-up, is not liable t'o derangement, but is so constructed vthat the parts are accessible for repair and renewal.

A further and important object is to provide valve mechanism that will properly shut off the -flow of the lubricant when closed, the valve having a rectilinear move- -ment toward andvfrom its seat, 'and being .allowed suiiicient play to eEect a proper `seating action.

Inthe embodiment illustrated in the accompanying drawings Figure 1 is a longitudmal sectional'vlew through a `hand oiler equipped with the novel valve mechanism.

Fig. 2 is a sectional view on the line 2--2 of Fig. 1. f

Fig. 3 is a detail sectional view through the reservoir body-at right angles to Fig. 1.

Fig. 4 is a detail view on an'enlarged scale of the valve and valve seat.

Fig. 5 isr a detail sectional view of the valve.

Fig. 6 is a detail sectional view on an enlarged scale through the coupling Vbetween the spout and can or reservoir body.

Fig. 7 is avdetail sectional view von th line 7-7 of Fig. 1,.and y v Fig. `8 is a detail view of 'the operating handle.

Similar reference numerals designate corresponding vparts in all the figures of the drawings.

In the embodiment disclosed, the can or reservoir body 9 may be of any desired structure, and. is provided-with an upstanding threaded nipple 10 terminating.v in an inset wall 11 spaced from the threaded po-rtion. .Avtaperedspout 12 is employed havling its larger end crimped or otherwise formed, to produce parallel opposite sides,

as indicated at 13. On this portion 13 is fixed, as by brazing, welding, soldering or the like, a reinforcing collar 14 having at its outer end an outstanding stop flange 15. The said larger end 13--14 iits snugly within the inset wall 11 of the nipple, as clearly shown in Fig. 6, and interposed between the upper end of said nipple and the flange l5, is a packing gasket 16. A threaded cap 17 screwed upon the nipple 10 has an linset flange 18 that overlies the stop flange 15, and is preferably corrugated, as shown at 19 to stiflen the same.

In the outer portion of the spout l2 is a valve seat member, preferably constructed of sheet` metal, and comprising a transverse partition 20 having an outwardly tapered discharge opening forming the seat, this partition alsov having anv inwardly extending annular flange 21. The flange fits snugly against-the walls of the spout 12 and the seat member thus produced is suitably fixed within said spout, as for examplebyhaving the walls of the spout indented, as shown at 23 on opposite sidesof the member. A valve stem 24 is slidably mounted in the stem and extends into the can body 9, the outer end of this stemhaving a head 25 von which is mounted .a valve in the form of a hollow body 26 that surrounds the head 25, and has a slight amount of play thereon. Thestem furthermore hasl secured to it a guide spider 27 adjacent tothe head, and serving to maintain the stem in centered relation, this .spider sliding within the spout 12, as will be readily understood.

The can body or reservoir -is provided with a transverse supporting bar' 28 fixed at its ends to the walls thereof, and carrying -an oii'set vkeeper 29 constituting a guide in which the inner end of the stem is slidably engaged, the rear wall 30 of-said guide being rounded, as clearly shown in Fig. 3 so as to reduce the bearing surface for the stem.

Journaled in one wall of the body 9 isa 100 rock shaft 31, the inner end ofv which 1s rotatably mounted in the supporting bar 28. The journal bearing for the outer end of the shaft is in the form of a packing gland comprising a casing 32 through which 105 yis provided with a suitable operating handle ',110

35, and its inner end has fixed thereto a gear segment 36 that extends into the guideway formed between the keeper 29 and supporting bar 2S. The lower end 37 of the valve stem 24 is smooth, and just above said smooth portion, said stem is provided with rack teeth 3S arranged to mesh with the teeth of the gear segment 36 when the rock shaft is rotated. In normal condition, however, as shown in Fig. 3, the teeth are out of mesh so that the valve stem 24 can be withdrawn from the guideway and the reservoir body 9. To maintain the parts in the position shown in Fig. 3,A a coiled spring 39 surrounds the shaft 31, and has one end connected as shown at @LO to a rearwardly extending finger l1 on the gear segment, the other end of the shaft being engaged, as illustrated at 42, with the supporting bar 28.

Briefly described, the operation of the device is as follows: With the parts as shown in Figs. 1, 3 and 4, the valve is closed, the lowermost teeth 3S bearing upon the teeth of the gear segment 36, so that the valve is held closed and cannot be accidentally opened except against the action of the spring. If, however, the handle 35 is pressed downwardly, the gear segment will be turned, causing the teeth to intermesh and moving the valve stem 24 inwardly. This causes the valve to be unseated to permit the outflow of lubricant. Upon releasing the handle 35, the spring 39 willreact to close the valve.

With this construction, it will be evident that the valve and valve stem have a strictly rectilinear movement, the valve stem and valve, even when the latter is o-pened, is maintained centrally within the spout, so that it will not materially interfere with the flow of the oil, and in addition it prevents binding at the inner end of the stem. The valve will always seat itself properly, and any slight inaccuracy in the valve seat will be accommodated by the play of the valve 26 upon the head 25. When the spout is removed, the valve and stem can also be readily detached inasmuch as the teeth 38 and gear segment 36 will be out of mesh. Furthermore the structure insures proper coperation of the valve and valve Seat even if there is a variation in the position of the valve, for when the spout is screwed down the valve will seat itself and any excess length of the stem will cause the teeth to intermesh and turn the gear segment `slightly to accommodate the same. The parts obviously are simple in form and can be easily and cheaply manufactured and assembled, their proper functioning after assembly being assured 'because of the relation as above set forth.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
